This Kit Works!

October 7, 2012

This kit is a great kit if you want to replace your radio in your Chevy Sonic without loosing any of the features you paid for. My Sonic has BlueTooth and Stering Wheel controls as well as OnStar. By using this kit I retained all my previous features while adding a quality car audio system. The instructions can be quite confusing at times, but I was able to work through them. If you have no electronics or car audio experience I would not recommend you try to use this kit as it may cause problems with the confusion. The paint of the kit matches the factory paint very well.

Why did you choose this?

I recently found out I was getting a new stereo as a gift for christmas, so I knew I would need the new dash kit in order to put it in.

Great Product and great price

What size screen fits in this?
A shopper on Dec 3, 2015
Best Answer: Hello,

Headunits are NOT categorized by the size of their screen, but instead by the size of the chassis. In car audio there are TWO 'standardized sizes' for headunits: Single DIN & Double DIN . With that said, this kit is able to accommodate BOTH.
